Abstract

PURPOSE: To obtain the title monofilament useful for fishing lines, etc., having excellent toughness, impact resistance and transparency by sticking an expanding agent to the surface of polyvinylidene fluoride having high birefringence and heat-treating in an inert gas.
CONSTITUTION: For example, in production of high-knot strength polyvinylidene fluoride having ≥1.0 intrinsic viscosity index measured in 0.4g/cc DMF solution, an expanding agent such as acetone is stuck to the surface of polyvinylidene fluoride having ≥25×10-3 birefringence, the polyvinylidene fluoride is heat- treated in an inert gas such as air under a condition of temperature (T°C) of the inert gas, diameter (Dmm)of monofilament and treating time (τ time) satisfying 68D/(T-25)≤τ≤680D/(T-25) and 1,000≥T≥200 to give the objective monofilament.
